1220531-63-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1220531-63-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,5,3 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1220531-63:
(9*1)+(8*2)+(7*2)+(6*0)+(5*5)+(4*3)+(3*1)+(2*6)+(1*3)=94
94 % 10 = 4
So 1220531-63-4 is a valid CAS Registry Number.

Organocatalytic Approach for Assembling Flavanones via a Cascade 1,4-Conjugate Addition/oxa-Michael Addition between Propargylamines with Water

He, Xinwei,He, Xinwei,Xie, Mengqing,Li, Ruxue,Choy, Pui Ying,Tang, Qiang,Shang, Yongjia,Kwong, Fuk Yee

, p. 4306 - 4310 (2020/06/05)

A DBU-catalyzed one-pot cascade reaction of propargylamines and water for the synthesis of flavanones has been developed. This process proceeds via a sequence of 1,4-conjugate addition of water to alkynyl o-quinone methide (o-AQM), followed by the alkyne-allene isomerization and subsequent intramolecular oxa-Michael addition. This strategy provides a convenient method for accessing a broad range of flavanones in good to excellent yields with good functional-group tolerance, in particular, the reactive halo functional groups.

Fast and efficient synthesis of flavanones from cinnamic acids

Bedane, Kibrom Gebreheiwot,Majinda, Runner R. T.,Masesane, Ishmael B.

, p. 1803 - 1809 (2016/11/18)

A fast and efficient synthesis of flavanones from cinnamic acids in three steps has been developed. First, the cinnamic acid was converted to cinnamyol chlorides using SOCl2. The acid chlorides were then treated with substituted phenols in BF3· OEt2to furnish corresponding chalcones in 42(75% yields. Base-catalyzed cyclization of the chalcones at room temperature afforded corresponding flavones in 85–95% yields. The conversion of the cinnamic acid derivatives to corresponding chalcones was found to be sensitive to the position and nature of the substituents on the aromatic rings.

Simple and efficient one step synthesis of functionalized flavanones and chalcones

Albogami, Abdullah Saad,Karama, Usama,Mousa, Ahmed Amine,Khan,Al-Mazroa, Sara Abdullah,Alkhathlan, Hamad Z.

, p. 619 - 626 (2012/10/30)

A facile and highly efficient microwave-assisted synthesis of functionalized chalcones and flavanones based on the Claisen-Schmidt condensation reaction is reported. The method describes the synthesis of flavanones in single step with excellent yield and it was revealed that position and number of substituents on acetophenones and aromatic aldehydes played a very crucial and key role in the construction of flavanone derivatives. Among the thirty two synthesized compounds, five chalcones and one flavanone were novel compounds.
